Re: HELP! Where can I get a 15'x12' foot 1018 Steel 1/8" Plate?
The times I have needed odd plates and sheets (larger than the readily available max of 5 x 12) I have just welded pieces together. If the project requires a 'seamless' surface then you will simply have to spend more time and labor grinding and finishing. Which might indeed make it worth it to pay the extra to the mill for a specialty item.
And something that size (12 x 15) would be a real problem to ship/deliver.
